Note about Preliminary Analyses

Please note that all analyses detailed herein are preliminary and subject to change.

All analyses are performed in Microsoft Open R (Microsoft, 2020; R Core Team, 2020) with Intel MKL. The following packages were used:

• MASDERtools version 0.0.5.2, a custom package for these analyses, which explicitly imports the following packages (some of which should be cited):
  • IRT packages: Gifi, ltm, mirt
  • EFA packages: networkD3 (Sankey diagrams)
  • Other formatting packages: gridExtra, htmlwidgets, htmltools
• IRT packages: ltm, which - despite being imported by MASDERtools - needs to be loaded in this analysis to avoid an error
• EFA packages: nFactors
• CFA packages: lavaan, semPlot, semTools
• Other analysis packages: psych (for reverse coding, identifying multivariate outliers, etc.)
• Other miscellaneous packages: readxl (for reading data), kableExtra (for colour-coding tables)

Reading and Cleaning Data

The file 01 Data Cleaning (Run First).Rmd handles reading and cleaning the data.

Item Response Theory

Dimensionality

First, we need to assess the dimensionality of each scale; we need each scale to be unidimensional. Before this can be done, we need to determine if treating the response scale should be treated as linear or ordinal.

Based on the loss functions, the results are similar for a linear and an ordinal approach are similar. Therefore the linear approach is used (more parsimonious).

Summary of Dimensionality

The following items do not load with the others:

• Pilot 2 (Fall 2021)
  • Attain: {4}, {others}
  • CostX: {1, 10}, {2, 5, 7, 11}, and {others}
  • DifficultyX: {5}, {1, 6, 8}, {2, 3, 4, 7, 9}
  • GoalX: {4}, {10, 11}, {2, 3, 12, 13}, {1, 5, 6, 7, 8, 9}
  • Expectancy: {5}, {1, 2, 3, 4, 6}
  • IntEnj: {1, 3, 5, 6, 9}, {2, 4, 7, 8}
  • Utility: {7, 8, 9, 10, 11}, {1, 2, 3, 4, 5, 6}
  • AcadSCX: {10}, {6, 9, 13, 14}, {others}

Based on examining the above graphs and the item text, we determine sets of items to drop.

drop_items_a <- list(c(4), # Attain
                     c(1, 10), # CostX
                     c(1, 6, 8, 5), # DifficultyX
                     c(4, 10, 11), # GoalX
                     c(5), # Expectancy
                     c(NULL), # IntEnj
                     c(NULL), # Utility
                     c(10, 6, 9, 13, 14)) # AcadSCX

drop_items_b <- list(c(4, 8, 3, 10), # Attain
                     c(1, 10), # CostX
                     c(1, 6, 8, 5), # DifficultyX
                     c(4, 10, 11), # GoalX
                     c(5), # Expectancy
                     c(NULL), # IntEnj
                     c(NULL), # Utility
                     c(10, 6, 9, 13, 14)) # AcadSCX

These items should be investigated for inclusion/exclusion further.

Polytomous IRT modeling

IRT is a framework for analyzing categorical data, including polytomous responses such as to Likert-type items. IRT analyses presume unidimensional scales (except in multidimensional IRT); the dimensionality analysis conducted above suggests that there are reasonably unidimensional sets of items to examine. Three models will be considered:

• Partial Credit Model (PCM; PCM)
• Generalized Partial Credit Model (GPCM; GPCM)
• Graded Response Model (GRM; GRM)

All three models are appropriate for polytomous responses such as those from the S-SOMAS scales (e.g., @Mair2018).

In the future, multivariate IRT models should be considered.

The ltm package (Rizopoulos, 2006) is used in the model comparison analysis; the mirt package (Chalmers, 2012) is used for the other IRT analyses. Both packages are accessed through the MASDERtools package.

Not all items have responses in each category, which is a requirement to run IRT. We will drop these items now. Future data collection may result in changing this.
